IMPROVEMENT lN MODE OF ATTACHING THlLLS AND POLES TO VEHICLES.

To all whom it may concern.-

Be it known that I, ABRAM J. GIBSON, of Clinton,in the county of WVorcester and State of Massachusetts, have invented a new and useful Improvement in the Mode of Attaching Thills and Poles to Vehicles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, which represents a side View of the thills attached by spring to the axle, drawn to full size.

The nature of my invention consists in attachin g the thills or poles to vehicles by means of steel springs, whereby I am enabled to prevent the Wearing and rattling usually attendant upon attaching thills or poles to vehicles in the usual way, at the same time avoiding the danger consequent upon the Working and wearing of bolts and nuts or other fastenings in general use, the draft being directly upon the axle and the cross-bar. By means of this attachment I am enabled to give any required position to the thills or poles, and also to give the necessary pressure downward to the thills or the upward pressure to the poles, in order to keep the harness steady upon the horse.

Having pointed out the nature of my invention and some of the advantages of the same, I will now proceed to describe its several parts. y

a represents the thills, b the forward axle, and c the springs which connect the thills with the forward'axle b. The springs c are made of hardened steel, thick near the ends attached to the thills and axle and diminished toward the center, so that the elastic part is in the center of the spring. By giving the requisite curve to the springs 0 they may be elevated or depressed at pleasure whenthe horse is detached from the carriage. I do not intend to confine myself to the material used in the makingof the springs o, as brass or any other material of an elastic nature may be used to good advantage; neither would I confine myself to the precise point of attaching the thills, as they can be attached to other parts of the vehicle by means of the springs c with equal benefit.

The branches of the spring 0 are connected by a strap'm, as shown in the drawing.

The arrangement above described for thills is with slight modification the same as would be employed in the attachment of poles.

The axle referred to in the drawing is one with its arms bent forward and outward, though the same mode of attachment is applicable to the common or any other axle.

Having described the several parts of my invention, what I claim as new, and desire to secure by Letters Patent, is

The manner of attaching thills or poles to vehicles by means of a steel spring or its equiv- V alent, substantially as set forth.

In testimony whereof I have hereunto signed my name before two subscribing wit.- nesses.
